Analysis

Last time I tested ext4, xfs and btrfs, deletions really lagged behind. Now, it looks like btrfs is quite a bit more robust. Additionally, there are better repair and recovery tools which were basically missing before. btrfs doesn’t lag behind like it used to, and while it is a little slower in some cases, it’s only a few percent. However, it makes up for that with some of the random and sequential creation and deletions.

Rough analysis at this point – if you need a versioning filesystem and don’t mind being a bit on the bleeding edge, btrfs has made substantial strides.

Updated Analysis

For the hardware in question, it appears that the larger block sizes with Bonnie++ don’t benefit things, but, make sure you test with your workload.
